Table 2

Inhibitory effect of α-glucosidase activity of Nopal dry powder (NPDP) and water extract (NPWE).

Extracts	Concentration (μg/mL)	Inhibition (%)	IC50 (μg/mL)^(1)
Nopal dry powder	100	43.59
	50	41.50
	25	23.52
	10	8.67
Nopal water extract	100	53.23
	50	47.22
	25	44.65
	10	28.89
	5	19.02
	2.5	5.12
Acarbose^(2)	100	68.39
	50	59.41
	25	49.34
	10	39.32
	5	34.41
	2.5	16.46

he IC₅₀ value was defined as the half-maximal inhibitory concentration and mean of 3 duplication analyses of each sample.
carbose was positive control.
